Scaling Capitalist Class Relations: Commercial Property Development in Tampa, Florida

We test the relationship between the implied cost of capital and two agency problems, free cash flows and overinvestment. We show that free cash flows have a significant negative impact on the implied cost of capital, but overinvestment has a significantly positive impact. In addition, the pay-for-performance sensitivity has a negative effect but the sensitivity of volatility has a significantly positive effect on the implied cost of capital. After taking the incentives into account, we find that the significance of the impact from both agency problems still exists. Finally, we conclude that well-designed executive compensation should focus on reducing overinvestment and the sensitivity of volatility

Data Behind the Walls An Advanced Architecture for Data Privacy Management

In today's highly connected society, we are constantly asked to provide personal information to retailers, voter surveys, medical professionals, and other data collection efforts. The collected data is stored in large data warehouses. Organisations and statistical agencies share and use this data to facilitate research in public health, economics, sociology, etc. However, this data contains sensitive information about individuals, which can result in identity theft, financial loss, stress and depression, embarrassment, abuse, etc. Therefore, one must ensure rigorous management of individuals' privacy. We propose, an advanced data privacy management architecture composed of three layers. The data management layer consists of de-identification and anonymisation, the access management layer for re-enforcing data access based on the concepts of Role-Based Access Control and the Chinese Wall Security Policy, and the roles layer for regulating different users. The proposed system architecture is validated on healthcare datasets.Comment: 7 page

Cardiac, Hepatic and Renal Dysfunction and IL-18 Polymorphism in Breast, Colorectal, and Prostate Cancer Patients

Introduction: The present study aimed to determine the alterations in the serum levels of tumor markers used to evaluate cardiac, renal and liver function, and detect the interleukin (IL)-18 rs1946518 polymorphism in breast (BC), colorectal (CRC) and prostate cancer (PCa) patients. Methods: Blood samples were collected from 65 female BC, 116 CRC, 79 PCa and 88 myocardial infarction (MI) patients, and 110 healthy individuals to determine the concentration of tumor and cardiac markers. Furthermore, the IL-18 rs1946518 polymorphism was assessed using amplification refractory mutation system (ARMS)-PCR. Results: The serum levels of the tumor markers cancer antigen 15-3 (CA 15-3), carbohydrate antigen 19-9 (CA 19-9), carcinoembryonic antigen (CEA) and total prostate-specific antigen (TPSA) were significantly increased in cancer patients compared with healthy controls. Furthermore, the activity of high-sensitivity cardiac troponin T (hs-cTnT) and creatine kinase‑myocardial band (CK-MB) was enhanced in MI patients, however, their activity was unchanged in cancer patients. The activity of alkaline phosphatase (ALP), and the serum concentration of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and urea were markedly elevated in CRC and PCa patients, respectively, compared with the control group. Although, no significant differences were observed in the -607 C/A polymorphism and allele frequency of IL-18 among BC, CRC patients and healthy individuals, the odds ratio (OR) was 1.75 for both C and A allele in BC patients. Therefore, the -607 C/A polymorphism could be considered as a risk factor for BC. Conclusion: The aforementioned results suggested that tumor markers could be considered as excellent biomarkers for the early detection of BC, CRC and PCa, whereas the concentration of liver enzymes could serve as an alternative indicator for the diagnosis of CRC and PCa. Additionally, the rs1946518 polymorphism in the IL-18 gene could be considered as a risk factor for the occurrence of BC, CRC and PCa

Checklist of the Pleistocene marine molluscs of Praínha and Lagoínhas (Santa Maria Island, Azores).

A critical review of the reported Pleistocene species of and Lagoinhas (Santa Maria Island, Azores) is provided, new data increasing the marine molluscan fauna to 95 taxa (80 Gastropoda and 15 Bivalvia). Six of the reported taxa are considered dubious records (5 Gastropoda, 1 Bivalvia). The stratigraphic sequence of Praia Formosa is composed of two main units, about 2-4 meters above present-day sea level. In the lower unit, Patella ulyssiponensis dominates the fossil assemblage of the basal calcareous conglomerate while Myoforceps arustatus (Dillwyn, 1817) dominates the assemblage associated to a calcareous algae mat. Above a non-depositional hiatus surface, a sandy beach deposit mainly composes the upper unit. Its fossil assemblages are dominated by large amounts of Eruilin castanea (Montagu, 1803) and, in a less extent, Lucinella diwricntn (Linnaeus, 1758) and Ensis minor (Chenu, 1843). The stratigraphic sequence of Lagoinhas, located 7.4 m above present-day sea level, is also composed of two units. A basal conglomerate is fossilized by or passes laterally to a calcareous algae mat, dominated by Myoforceps aristatus and with abundant Calliostoma pecimens. As at Prainha, these lower units are covered by a highly fossiliferous sandy bach deposit, though thinner, in which Ervlie castanea is the dominant species. Some species with Caribbean or West African affinities, the "Strombus bubonius accompanying fauna" (Garcia-Talavera, 1990), were found in the lower layers. The upper layer malacofauna is mainly related to the Mediterranean faunas, similarly to what happens nowadays (Ávila, 2000)

TPPSO: A Novel Two-Phase Particle Swarm Optimization

Particle swarm optimization (PSO) is a stout and rapid searching algorithm that has been used in various applications. Nevertheless, its major drawback is the stagnation problem that arises in the later phases of the search process. To solve this problem, a proper balance between investigation and manipulation throughout the search process should be maintained. This article proposes a new PSO variant named two-phases PSO (TPPSO). The concept of TPPSO is to split the search process into two phases. The first phase performs the original PSO operations with linearly decreasing inertia weight, and its objective is to focus on exploration. The second phase focuses on exploitation by generating two random positions in each iteration that are close to the global best position. The two generated positions are compared with the global best position sequentially. If a generated position performs better than the global best position, then it replaces the global best position. To prove the effectiveness of the proposed algorithm, sixteen popular unimodal, multimodal, shifted, and rotated benchmarking functions have been used to compare its performance with other existing well-known PSO variants and non-PSO algorithms. Simulation results show that TPPSO outperforms the other modified and hybrid PSO variants regarding solution quality, convergence speed, and robustness. The convergence speed of TPPSO is extremely fast, making it a suitable optimizer for real-world optimization problems

Coralline-algal framework in the quaternary of prainha (Santa Maria island, Azores)

© Instituto Geológico y Minero de España.At the south coast of the island of Santa Maria (Azores, Portugal) a coralline-algal framework emerges near the base of a Quaternary succession. It is located about 2 m above the present mean sea level, extends for near 200 m along the littoral zone, and has a maximum thickness of 60 cm. The main framework builders are coralline red algae (Corallinaceae, Rhodophyta). Mollusc shells, vermetid tubes and bryozoans are the secondary framework builders. The coralline assemblage is composed of Spongites fruticulosus, with some Neogoniolithon brassica-florida, Lithophyllum incrustans and Titanoderma pustulatum. The morphological network and taxonomic composition show close analogies with the coralline algal assemblages of the Mediterranean and west Atlantic, formed at sea level in narrow tide amplitudes and moderate hydrodynamics
